The EClamp

for protection and termination of low speed or full

speed Universal Serial Bus (USB) ports. Each device will

provide termination, filtering, and ESD protection for

one upstream USB port on cellular phones and other

portable electronics. This state-of-the-art device utilizes

solid-state silicon-avalanche technology for superior

clamping performance and electrical characteristics.

Line termination is achieved with 22 Ohm series

resistors on both the D+ and D- USB lines. TVS diodes

are also included on each data line for ESD protection

in excess of ±15kV (air discharge) and ±8kV (contact

discharge) per IEC 61000-4-2, level 4. An additional

TVS diode connection is included for protection of the

voltage (VBus) bus. The 1.5k Ohm pull-up resistor is

included on one of the USB data lines to identify the

equipment as either a full-speed (connected to D+ line)

or low-speed (connected to D- line) device.

The EClamp2522P is in a 6-pin, RoHS compliant,

SLP1616P6 package. It measures 1.6 x 1.6 x

0.60mm. The leads are spaced at a pitch of 0.5mm

and are finished with lead-free NiPdAu. The small

package makes it ideal for use in portable electronics

such as cell phones and digital still cameras.
